Old iTunes on iMac power pc won't sync with new iPhone ios7

Question

I have an old power pc iMac with all my iTunes library on it, I also have a newer intel dual core iMac & an iPhone 4. To add a playlist to my iPhone I need to be able to sync with iTunes on my old power pc iMac but the versions of iTunes are no longer compatible & I can't update my power pc iMac as it won't run the later versions of iTunes. If I connect my iPhone to my dual core iMac it will erase all the stuff I put on before it was incompatible. Is there a way that I can get all the devices to talk to each other ( particularly to share my iTunes library on all 3 devices) ?

Answer 1

The short answer is that you'll have to start syncing your phone with the Intel iMac. Probably the easiest solution is to move your music library to the newer computer with an external hard drive (unless the computers are connected via ethernet cable filesharing would be very slow). Since I don't have access to such an old computer (and the version of iTunes it is running) I'm not sure if you can use Home Sharing to share the iTunes library of the old Mac with the new one and whether that would solve your problem.
